BACKGROUND

The invention relates generally to ground working equipment, such asagricultural equipment, and more specifically, to a conduit system for apneumatic distribution system of an agricultural implement.

Generally, planting implements (e.g., planters) are towed behind atractor or other work vehicle via a mounting bracket secured to a rigidframe of the implement. These planting implements typically includemultiple row units distributed across the width of the implement. Eachrow unit is configured to deposit seeds at a desired depth beneath thesoil surface, thereby establishing rows of planted seeds. For example,each row unit may include a ground engaging tool or opener (e.g., anopener disc) that forms a seeding path for seed deposition into thesoil. In certain configurations, a gauge wheel is positioned a verticaldistance above the opener to establish a desired trench depth for seeddeposition into the soil. As the implement travels across a field, theopener excavates a trench into the soil, and seeds are deposited intothe trench. In certain row units, the opener is followed by a packerwheel that packs the soil on top of the deposited seeds.

Certain planting implements include a remote seed tank, and a pneumaticdistribution system configured to convey seeds from the tank to each rowunit. For example, the pneumatic distribution system may include aninductor box positioned beneath the seed tank. The inductor box isconfigured to receive seeds from the tank, to fluidize the seeds into anair/seed mixture, and to distribute the air/seed mixture to the rowunits via a network of pneumatic hoses/conduits. Each row unit, in turn,receives the seeds from the pneumatic hoses/conduits, and directs theseeds to a metering system. The metering system is configured to providea flow of seeds to a seed tube for deposition into the soil. Byoperating the metering system at a particular speed, a desired seedspacing may be established as the implement traverses a field.

In planting implements with an inductor box, a distance between theinductor box and the row units varies along the width of the plantingimplement. Thus, the network of pneumatic hoses/conduits includescertain sections with short runs between the inductor box and row unitsnear the inductor box, and certain sections with long runs between theinductor box and row units located farther from the inductor box.Unfortunately, due to the length of the conduits, longer runs have lessairflow than shorter runs. Accordingly, seeds may not be uniformlydistributed to the row units. For example, row units closer to theinductor box may receive too many seeds, while row units farther fromthe inductor box may receive too few seeds.

DETAILED DESCRIPTION

FIG. 1 is a perspective view of an embodiment of an agriculturalimplement 10 configured to deposit seeds into a soil surface. In theillustrated embodiment, the implement 10 is configured to be towed alonga direction of travel 12 by a work vehicle, such as a tractor or otherprime mover. The work vehicle may be coupled to the implement 10 by ahitch assembly 14. As illustrated, the hitch assembly 14 is coupled to amain frame assembly 16 of the implement 10 to facilitate towing of theimplement 10 in the direction of travel 12. In the illustratedembodiment, the frame assembly 16 is coupled to a tool bar 18 thatsupports multiple row units 20. Each row unit 20 is configured todeposit seeds at a desired depth beneath the soil surface, therebyestablishing rows of planted seeds. The implement 10 also includes seedtanks 22, and a pneumatic distribution system configured to convey seedsfrom the tanks to the row units 20. In certain embodiments, thepneumatic distribution system includes an inductor box positionedbeneath each seed tank 22. Each inductor box is configured to receiveseeds from a respective tank, to fluidize the seeds into an air/seedmixture, and to distribute the air/seed mixture to the row units 20 viaa network of pneumatic hoses/conduits.

In certain embodiments, each row unit 20 includes a residue manager, anopening assembly, a seed tube, closing discs, and a press wheel. Theresidue manager includes a rotating wheel having multiple tillage pointsor fingers that break up crop residue, thereby preparing the soil forseed deposition. The opening assembly includes a gauge wheel and anopener disc. The gauge wheel may be positioned a vertical distance abovethe opener disc to establish a desired trench depth for seed depositioninto the soil. As the row unit travels across a field, the opener discexcavates a trench into the soil for seed deposition. The seed tube,which may be positioned behind the opening assembly, directs a seed froma metering system into the excavated trench. The closing discs thendirect the excavated soil into the trench to cover the planted seed.Finally, the press wheel packs the soil on top of the seed with adesired pressure.

While the illustrated implement 10 includes 24 row units 20, it shouldbe appreciated that alternative implements may include more or fewer rowunits 20. For example, certain implements 10 may include 6, 8, 12, 16,24, 32, or 36 row units, or more. In addition, the spacing between rowunits may be particularly selected based on the type of crop beingplanting. For example, the row units may be spaced 30 inches from oneanother for planting corn, and 15 inches from one another for plantingsoy beans.

The pneumatic distribution system may include a conduit system havingmultiple conduit assemblies. Each conduit assembly couples an outputport of the inductor box to a respective row unit. In certainembodiments, a first diameter of a first conduit assembly may be largerthan a second diameter of a second conduit assembly to facilitate aneven distribution of agricultural product from the inductor box to therow units. Thus, particularly selecting the diameter of conduitassemblies that extend between the inductor box and the row units maycompensate for variations in distance between the row units and theinductor box, thereby facilitating substantially uniform distribution ofagricultural product through the pneumatic distribution system.

FIG. 2 is a schematic diagram of an embodiment of a pneumaticdistribution system 24 having two configurations of conduit assemblies.An inductor box 26 is configured to receive an agricultural product 28from the seed tank 22. Moreover, the inductor box 26 is configured toreceive an airflow 30, such as from an air supply. The inductor box 26combines the agricultural product 28 with the airflow 30 and directs thecombined agricultural product 28 and the airflow 30 through a conduitsystem 32 to the row units 20. Specifically, output ports 34 of theinductor box 26 direct the combined agricultural product 28 and theairflow 30 to the conduit system 32 for routing to the row units 20. Therow units 20 are configured to receive the agricultural product 28 andthe airflow 30, and to deposit the agricultural product 28 into soil.

The conduit system 32 is configured to direct the agricultural product28 and the airflow 30 from the output ports 34 to the row units 20. Inthe illustrated embodiment, the conduit system 32 includes multipleconduit assemblies 36 or 38. In particular, the conduit system 32includes one of the conduit assemblies 36 and 38 for each row unit 20.For simplicity, only four row units 20 are illustrated; however, theconduit system 32 may couple the inductor box 26 to more or fewer rowunits 20. The conduit assembly 36 includes a hose 40 extending betweenthe output port 34 and the row unit 20. In certain embodiments, the hose40 is a flexible hose to facilitate routing between the output port 34and the row unit 20 along a tortuous path. The hose 40 includes an inlet42 coupled to the output port 34, and an outlet 44 coupled to the rowunit 20. An inner diameter 46 of the inlet 42 is substantially equal tothe inner diameter 48 of the outlet 44. For example, in certainembodiments the inner diameter 46 of the inlet 42 and the inner diameter48 of the outlet 44 may both be approximately 2.54 cm (e.g., 1.0inches). As may be appreciated, the inner diameter 46 of the inlet 42and/or the inner diameter 48 of the outlet 44 may be the same as theinner diameter of the hose 40.

The conduit assembly 38 includes a first hose 50, a tube 52, and asecond hose 54. The tube 52 extends between the first hose 50 and thesecond hose 54. In certain embodiments, the first hose 50 and the secondhose 54 are both flexible hoses that facilitate routing between theoutput port 34 and the row unit 20. Moreover, the tube 52 is lessflexible than the first and second hoses 50 and 54, and extends in asubstantially straight path. A coupler 56 is used to couple the firsthose 50 to the tube 52, while the tube 52 is inserted into the secondhose 54 to couple the second hose 54 to the tube 52. The conduitassembly 38 includes an inlet 58 that is coupled to the output port 34,and an outlet 60 that is coupled to the row unit 20. An inner diameter62 of the inlet 58 is less than an inner diameter 64 of the outlet 60.For example, the inner diameter 62 of the inlet 58 may be approximately2.54 cm (e.g., 1.0 inches), while the inner diameter 64 of the outlet 60may be approximately 3.18 cm (e.g., 1.25 inches). As may be appreciated,the inner diameter 62 of the inlet 58 may be substantially equal to theinner diameter of the first hose 50. Moreover, the inner diameter 64 ofthe outlet 60 may be substantially equal to the inner diameter of thesecond hose 54.

An inner diameter 66 of the coupler 56 is substantially equal to anouter diameter 67 of the first hose 50 and an outer diameter 68 of thetube 52 such that the coupler 56 may couple the first hose 50 to thetube 52. Furthermore, the outer diameter 68 of the tube 52 issubstantially equal to the inner diameter 64 of the second hose 54 suchthat the tube 52 may be inserted into the second hose 54. Moreover, theinner diameter 62 of the first hose 50 is substantially equal to aninner diameter 69 of the tube 52. Accordingly, the inner diameter 62 ofthe first hose 50 and the inner diameter 69 of the tube 52 are bothsmaller than the inner diameter 64 of the second hose 54. For example,the inner diameter 62 of the first hose 50 and the inner diameter 69 ofthe tube 52 may both be approximately 2.54 cm (e.g., 1.0 inches), whilethe inner diameter 64 of the second hose 54 may be approximately 3.18 cm(e.g., 1.25 inches). In addition, the inner diameter 48 of the hose 40is smaller than the inner diameter 64 of the second hose 54. Forexample, the inner diameter 48 of the hose 40 may be approximately 2.54cm (e.g., 1.0 inches), while the inner diameter 64 of the second hose 54may be approximately 3.18 cm (e.g., 1.25 inches).

As may be appreciated, the row units 20 coupled to the conduitassemblies 36 may be positioned closer to the inductor box 26 than therow units 20 coupled to the conduit assemblies 38. Conversely, the rowunits 20 coupled to the conduit assemblies 38 may be positioned fartherfrom the inductor box 26 than the row units 20 coupled to the conduitassemblies 36. For example, in an implement 10 having twelve rows, theconduit system 32 may be arranged as follows: row units 20 for rows fourthrough nine (e.g., positioned in the central portion of the implement10 proximate to the inductor box 26) may receive product from conduitassemblies 36, and row units 20 for rows one through three and tenthrough twelve (e.g., positioned laterally outward from rows fourthrough nine) may receive product from conduit assemblies 38. As anotherexample, in an implement 10 having sixteen rows, the conduit system 32may be arranged as follows: row units 20 for rows six through eleven(e.g., positioned in the central portion of the implement 10 proximateto the inductor box 26) may receive product from conduit assemblies 36,and row units 20 for rows one through five and twelve through sixteen(e.g., positioned laterally outward from rows six through eleven) mayreceive product from conduit assemblies 38.

In certain embodiments, an average diameter of the conduit assembliesmay vary between different conduit assemblies 36 and 38. For example,conduit assemblies 36 positioned in the central portion of the implement10 may have a smaller average diameter than conduit assemblies 38positioned laterally outward from the conduit assemblies 36. As may beappreciated, the average diameter of a conduit assembly may be aweighted average of the segments of the conduit assembly. For example,the average diameter of a conduit assembly having three segments may becalculated using the following formula:AD=(L_(s1)×ID_(s1)+L_(s2)×ID_(s2)+L_(s3)×ID_(s3))/(L_(s1)+L_(s2)+L_(s3)),where AD is the average diameter, L_(s1) is the length of first segment,L_(s2) is the length of the second segment, L_(s3) is the length of thethird segment, ID_(s1) is the inner diameter of first segment, ID_(s2)is the inner diameter of second segment, and ID_(s3) is the innerdiameter of third segment. As may be appreciated, the difference betweenaverage diameters of adjacent conduit assemblies may be significant toprovide more balance to the pneumatic distribution system 24. Forexample, in certain embodiments, there may be at least approximately aone percent difference between average diameters of adjacent conduitassemblies to provide more balance to the pneumatic distribution system24.

By using the conduit system 32 described herein, the pneumaticdistribution system 24 may operate in a more balanced manner. Forexample, by using smaller diameter hoses for the inner row units 20 andby using larger diameter hoses for the outer row units 20, agriculturalproduct may be more uniformly distributed among the row units 20. Thus,planting operations may be performed more efficiently with fewer clogsin the conduit system 32 and/or with more evenly spaced seeds throughoutthe field.

FIG. 3 is a schematic diagram of an embodiment of the pneumaticdistribution system 24 having three configurations of conduitassemblies. In the illustrated embodiment, the conduit assemblies 36 and38 are coupled to the row units 20. Furthermore, a conduit assembly 70is used to couple the inductor box 26 to outer most row units 20. Theconduit assembly 70 includes a first hose 72, a tube 74, and a secondhose 76. The tube 74 extends between the first hose 72 and the secondhose 76. In certain embodiments, the first hose 72 and the second hose76 are both flexible hoses that facilitate routing between the outputport 34 and the row unit 20. Moreover, the tube 74 is less flexible thanthe first and second hoses 72 and 76, and extends in a substantiallystraight path. A coupler 78 is used to couple the second hose 76 to thetube 74. Moreover, the first hose 72 may be coupled to the tube 74 usinga coupler, or any other suitable device. The conduit assembly 70includes an inlet 80 that is coupled to the output port 34, and anoutlet 82 that is coupled to the row unit 20. An inner diameter 84 ofthe inlet 80 is less than an inner diameter 86 of the outlet 82. Forexample, the inner diameter 84 of the inlet 80 may be approximately 2.54cm (e.g., 1.0 inches), while the inner diameter 86 of the outlet 82 maybe approximately 3.18 cm (e.g., 1.25 inches). As may be appreciated, theinner diameter 84 of the inlet 80 may be substantially equal to theinner diameter of the first hose 72. Moreover, the inner diameter 86 ofthe outlet 82 may be substantially equal to the inner diameter of thesecond hose 76.

An outer diameter 88 of the tube 74 and an outer diameter 89 of thesecond hose 76 are substantially equal to an inner diameter 90 of thecoupler 78, such that the tube 74 and the second hose 76 may be insertedinto the coupler 78 to couple the tube 74 to the second hose 76.Moreover, the inner diameter 91 of the tube 74 is substantially equal tothe inner diameter 86 of the second hose 76. Accordingly, the innerdiameter of the first hose 72 is smaller than the inner diameter 91 ofthe tube 74, and smaller than the inner diameter 86 of the second hose76. For example, the inner diameter 84 of the first hose 72 may beapproximately 2.54 cm (e.g., 1.0 inches), while the inner diameter 91 ofthe tube 74 and the inner diameter 86 of the second hose 76 may beapproximately 3.18 cm (e.g., 1.25 inches). In addition, the innerdiameter 48 of the hose 40 is smaller than the inner diameter 86 of thesecond hose 76. For example, the inner diameter 48 of the hose 40 may beapproximately 2.54 cm (e.g., 1.0 inches), while the inner diameter 86 ofthe second hose 76 may be approximately 3.18 cm (e.g., 1.25 inches).

As may be appreciated, the row units 20 coupled to the conduitassemblies 36 may be positioned closer to the inductor box 26 than therow units 20 coupled to the conduit assemblies 38, and the row units 20coupled to the conduit assemblies 38 may be positioned closer to theinductor box 26 than the row units 20 coupled to the conduit assemblies70. Conversely, the row units 20 coupled to the conduit assemblies 70may be positioned farther from the inductor box 26 than the row units 20coupled to the conduit assemblies 38, and the row units 20 coupled tothe conduit assemblies 38 may be positioned farther from the inductorbox 26 than the row units 20 coupled to the conduit assemblies 36. Forexample, in an implement 10 having twenty-four rows, the conduit system32 may be arranged as follows: row units 20 for rows eight throughseventeen (e.g., positioned in the central portion of the implement 10proximate to the inductor box 26) may receive product from conduitassemblies 36, row units 20 for rows seven and eighteen (e.g.,positioned adjacent laterally outward from rows eight through seventeen)may receive product from conduit assemblies 38, and row units 20 forrows one through six and nineteen through twenty-four (e.g., positionedlaterally outward from rows seven and eighteen) may receive product fromconduit assemblies 70. As another example, in an implement 10 havingthirty-six rows, the conduit system 32 may be arranged as follows: rowunits 20 for rows fourteen through twenty-three (e.g., positioned in thecentral portion of the implement 10 proximate to the inductor box 26)may receive product from conduit assemblies 36, row units 20 for rowsnine through thirteen and twenty-four through twenty-eight (e.g.,positioned laterally outward from either side of rows fourteen throughtwenty-three) may receive product from conduit assemblies 38, and rowunits 20 for rows one through eight and twenty-nine through thirty-six(e.g., positioned laterally outward from rows nine and twenty-eight) mayreceive product from conduit assemblies 70.

In certain embodiments, an average diameter of the conduit assembliesmay vary between different conduit assemblies 36, 38, and 70. Forexample, conduit assemblies 36 positioned in the central portion of theimplement 10 may have a smaller average diameter than conduit assemblies38, and 70 positioned laterally outward from the conduit assemblies 36.Furthermore, conduit assemblies 38 that are nearer the central portionof the implement 10 may have a smaller average diameter than conduitassemblies 70 positioned laterally outward from the conduit assemblies38. As may be appreciated, the difference between average diameters ofadjacent conduit assemblies may be significant to provide more balanceto the pneumatic distribution system 24. For example, in certainembodiments, there may be at least approximately a one percentdifference between average diameters of adjacent conduit assemblies toprovide more balance to the pneumatic distribution system 24.

The pneumatic distribution system 24 may operate in a more balancedmanner by using the conduit system 32 described herein. For example, byusing smaller diameter hoses for the inner row units 20 and by usinglarger diameter hoses for the outer row units 20, agricultural productmay be more uniformly distributed. Thus, planting operations may beperformed more efficiently with fewer clogs in the conduit system 32and/or more evenly spaced seeds throughout the field.

FIG. 4 is a schematic diagram of an embodiment of the pneumaticdistribution system 24 having the conduit system 32 with a networkedconfiguration. As illustrated, a hose 92 extends between the output port34 of the inductor box 26 and a manifold 94 of the row unit 20. Incertain embodiments, the hose 92 is a flexible hose that facilitatesrouting between the output port 34 and the row unit 20. The hose 92 hasan inner diameter 96. In certain embodiments, the inner diameter 96 maybe approximately 3.18 cm (e.g., 1.25 inches). A hose 98 is also coupledto the manifold 94 and extends between the manifold 94 of the row unit20 and an adjacent row unit 20. In certain embodiments, the hose 98 is aflexible hose that facilitates routing between the manifold 94 and therow unit 20. The hose 98 has an inner diameter 100. In certainembodiments, the inner diameter 100 may be approximately 2.54 cm (e.g.,1.0 inches). This same routing pattern may be repeated for all row units20 of the implement 10 to produce the networked (e.g., spider)configuration. Accordingly, in certain embodiments, every other row unit20 is coupled directly to the inductor box 26 using the hose 92, whileeach remaining row unit 20 is coupled directly to a manifold 94 of anadjacent row unit 20 using the hose 98. The inner diameter 100 of thehose 98 may be smaller than the inner diameter 96 of the hose 92 tomaintain a desired velocity of agricultural product 28 and airflow 30through the hoses 92 and 98, and to reduce the possibility of the hoses92 and 98 from being clogged. By using this networked configuration,agricultural product 28 may be more evenly distributed in a field.

While certain embodiments have been described herein, other embodimentsmay also facilitate more efficient planting operations with fewer clogsand/or more evenly spaced seeds. For example, certain embodiments mayinclude a hose that increases in diameter from its inlet to its outlet.Moreover, other embodiments may include a hose that extends from alarger diameter outlet port of the inductor box to a row unit.

While only certain features of the invention have been illustrated anddescribed herein, many modifications and changes will occur to thoseskilled in the art.
